# Error with Fluent Forms

 * Hello and thanks for creating this plugin! 
   It’s like almost exactly what I’m
   looking for: first and last-touch attribution with server-side tracking and the
   consent feature is a bonus.
 * However, there are a few issues:
 * **Settings page** — For some reason the checkbox settings aren’t saving to the
   DB. I can only set the “enable_attribution” and “cookie_days”.
 * **Fluentforms** integration caused a **_fatal error_ **— Action should only accept
   1 argument:
   [https://fluentforms.com/docs/fluentform_form_element_start/](https://fluentforms.com/docs/fluentform_form_element_start/)
 *     ```wp-block-code
       FILE: class-fluent-forms-adapter.php (line 45) add_action( 'fluentform_form_element_start', array( $this, 'add_hidden_fields' ), 10, 2 );
       ```
   
 * Thanks!

 * Thanks for the detailed report and for linking the Fluent Forms hook docs.
 * I was able to confirm both issues.
    1. The settings page problem was on my side. The checkbox-based attribution settings
       were not being saved reliably, which is why only enable_attribution and cookie_days
       were persisting. I’ve corrected the settings registration/sanitization so those
       checkbox values save properly.
    2. You are also correct about the Fluent Forms fatal error. The adapter was registering
       fluentform_form_element_start with accepted_args = 2, but that action only passes
       1 argument. I’ve updated the hook registration and callback signature accordingly.
 * These fixes will be included in the next plugin update.
 * Thanks again for catching both issues.
